Turbocharged FD3S RX7 Cast Aluminum Lower Intake Manifold

Description

Key features:

• Dyno proven models featuring many variations to achieve best all around performance( not just top end RPM ). Units are equal length, and equal bend for proper balance between rotors. Tapered runner design, only slightly oversized from OEM. Does not hurt throttle response or bottom end/midrange performance. 
• 6 injector for semi pport, 4 for side port ( Billet 8AN fuel rail included with purchase).  Does not work with other fuel rails, as the fuel injector location has been changed for better fuel delivery. 
• All OEM emissions removed( for off road use only**) FC water passage removed.
• LIM flanges o-ringed( engine to LIM, and LIM to UIM). UIM only will not be O-ringed. 
• Extra material added so one can port match to a 13BRE or larger semi pport holes
• Mounting tabs for heat-shield
• Properly clears all of Turblown corresponding Cast FC & FD Turbo System

This might require new intercooler hot side piping possibly, as throttle body position is ever so slightly moved from OEM FD position to better accommodate even airflow distribution when purchased with the Turblown LIM. The UIM only is a drop in model.  Most IC piping has enough movement to accomodate no changes.  FC is moved higher and does not allow a top mount IC; FC will require IC piping change and a new oil filler neck assembly( including replacing the press in steel unit lower section with an FD unit). FC users require either using an FD throttle body & TPS, or DBW model. FC throttle body does not work with this unit. Stock FD twins will NOT fit this. 

S4 FC cars using OEM OMP will require linkage modifications, S5 do not.  OEM turbo coolant feed port is  removed from FC LIM; no coolant will be flowing through LIM like stock. Coolant feed will have to be pulled from rear iron or water pump housing. 

LIM will NOT work with off the shelf fuel rails, as we have changed the injector positions for optimum spray pattern position.  Fuel rail & LIM will come with plugs for those wanting to run less than 6 injectors. Fuel rail is for 14MM upper and lower o rings only 48mm total length Injector Dynamics injectors. No press in sleeves required. 

8AN ORB fuel rail does not come with AN adapters, or Pulsation Dampner. Fuel rail does not require 8AN lines, one can use 8AN ORB to 6AN adapters. 

Dummy injector blanks are available for those who do not want to run all injectors.

Supplied with all necessary mounting hardware

OR-131N6001 & OR-126N001 for off the shelf replacement O rings from MFPseals.
